This workshop brings together the country experts involved in the creation of the Migrant Social Protection (MigSP) dataset. The dataset covers national policies regarding immigrants' access to social protection benefits in 39 countries from 1980 to 2018. It collects information on immigrants’ access to non-contributory social assistance and unemployment insurance, as well as requirements for family reunification and the impact of unemployment and benefit receipt on residence statuses. At the workshop, the final dataset and plans for a future extension will be presented. There will also be thematic inputs by country experts covering various topics such as immigrant welfare rights in traditional sending countries, welfare rights of humanitarian and irregular migrants, indirect restrictions of rights and immigrants’ rights in residual welfare states as well as the impact of COVID-19 on immigrant welfare rights.
